PETER EGAN, OF BENNINGTON, VERMONT.

KNITTNG-IvACHINE-NEEDLE JACK.

Application led January 8, 1921.

To all whom t may concern:

.Be it known that l, PETER EGAN. a citizen of the United States, residing at Bennington, in the county of Bennington and State oi' Vermont, have invented certain new and useful improvements in a KnittingMachine- Needle Jack, oi: which the following is a specification.

This invention relates to knitting machine needle jacks and is designed as an improvement on the jack shown in Patent 825,017 to W. T. Barratt dated July 3, 1906.

The object of' the invention is to so construct ajack of this character whereby a needle may be readily inserted in the jack without the use of pliers, pinchers or other tools thereby avoiding danger ot breakage or bending of both the needle and the jack and facilitating the insertion of the needle.

Another object is to so construct a jack that the needle will be reliably held engaged with the jack preventing lateral movement of the needle relatively to the jack and the consequent bending or breaking of both the needle and the jack and insuring the regular engagement ot' the ack by its operating cam.

With these and other objects in view the `invention consists in certain novel features of construction as hereinafter shown and described and finally pointed out in the claims.

In the accompanying drawing:

Figure l represents a side elevation of a jack constructed in accordance with this invention with the needle shown applied.

Fig. 2 is a transverse section taken on the line 2 2 of Fig. l; and,

Fig. 3 is a rear edge view of the jack.

ln the embodiment illustrated a needle ljack l and a spring barb needle l0 are the needle and general structure of the jack corresponding to that shown in the patent above referred to. The jack l has the same S-shaped slot 2 extending transversely inward from the rear edge of the jack and the portion 3 ofthe rear edge in advance of said slot is made lower than the remaining edge a distance corresponding to the diameter of the shank l1 of the needle l0 so that the rear edge of the lower part of the jack and the rear edge of the needle shank 11 shown7 Serial No. 435,899.

will aline when the needle and ack are connected. The needle lO is equipped with a rightangularly extending S-shaped or reversely curved butt l2 of tortuous shape to substantially fit the slot 2 of the ack.

To enable the reversely curved butt to be inserted in the slot 2 without necessitating' the use of a tool the curved portion t is made sufficiently;Y small to reduce the cam-like gripping action between this element and the needle butt so that the butt may be readily inserted with the fingers in said slot. This is accomplished by cutting away the edge 3 ot the jack adjacent the slot 2 for a short distance as shown at 5 while said edge in advance ot said cutaway portion is grooved longitudinally to form a seat 6 for the needle shank as shown in Figs. l and 3 so i that the needle will be held against lateral movement7 the slot 2 operating to hold it against rearward movement.

It will thus be seen that this slight change in the jack accomplishes an important and novel result, greatly enhancing the value of the jack by adapting` it to reliably hol-d a needle firmly engaged therewith and to provide for the insertion of the needle by hand without. the use of any tools whatever.

This jack not only reliably holds aneedle engaged therewith and permits its ready in` sertion without the use of tools but also provides for the ready removal ot the needle by simply lifting it rearwardly a sumcient distance to clear the walls of the groove or seat 6 and then swinging it laterally to disengage its butt from the jack.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specilicationJ but it will be understood that any modifications within the scope oi the claimed invention may be made in the construction without departing from the principle o1c the invention or sacrificing any of its advantages.

What I claim is:

l. A needle jack of the class described having a tortuous needle butt receiving slot extending transversely inward from its rear edge and a needle seat in said edge spaced from said slot to hold a needle against lat eral movement.

" tion of said edge shaped needle butt receiving. slot extendingy transversely inward `from ya needle seat 'termed in said edge in advance of saidslot, the portion o'tl said edge between said Seat and Slot being cutaway to Jiacilitate the insertion of the needle butt in the slot.

ln testimony whereof, l aflix my signa ture hereto. l,

PETER Begint its rear edge and lo
